Embodiment
Below, first execution mode of electric rotating machine of the present invention is described to Fig. 1～generator shown in Figure 3.
As shown in Figure 3, generator 1 comprises: housing 2; Rotating shaft 4, it is rotatably freely supported on this housing 2 through bearing 3A, 3B; Rotor 5, it is supported by this rotating shaft 4, and has magnetic pole; With stator 6, its space and this rotor 5 across Zhou Fangxiang is opposed.
And stator 6 is made up of stator core that is supported on said housing 27 and the stator winding 8 that is installed on this stator core 7.
In addition, in the execution mode of this execution mode and following explanation, stator core 7 is equivalent to core for rotary electric machine of the present invention, and stator winding 8 is equivalent to electric rotating machine winding of the present invention.
Said stator core 7 Zhou Fangxiang equally spaced be formed with a plurality of from said rotor 5 opposed internal side diameters to outside diameter and spread all over the slot for winding 7G of stator core 7 total lengths, be formed with wedge groove 7A at the peristome of slot for winding 7G.And, through chock 7W being inserted into this wedge groove 7A, can the stator winding that be installed in slot for winding 7G 8 is fixing.
On the other hand; Like Fig. 1 and shown in Figure 2; A plurality of wire conductor 10 that stator winding 8 will adopt known insulating material to implement wire insulation twine with known insulating material by many and form interlayer insulating film 11; And a plurality of wire conductor 10 that formed interlayer insulating film 11 are twined in its periphery adopt known insulating material to form main insulating layer 12, and then to have formed surface resistivity in the periphery of this main insulating layer 12 be the semiconduction insulating barrier 13 about 1k Ω.
The stator winding 8 that constitutes is like this built up two sections across the middle filler 14 that is made up of insulating material; Under this state; Through the formed protection insulating barrier 15 of known semiconduction insulating material that surface resistivity equates with semiconduction insulating barrier 13, stator winding 8 is inserted into the slot for winding 7G of stator core 7.After inserting stator winding 8, superimposed protection insulating barrier 15 surrounds stator winding 8, and filler 16 under the overlapping above that wedge that is made up of insulating material then, is inserted into chock 7W among the wedge groove 7A.
The semiconduction insulating substrate that is used to form said semiconduction insulating barrier 13 has semiconduction continuous slice (sheet) 13A; This semiconduction continuous slice 13A is through for example sneaking into carbon particle in the base material of polyester non-woven fabric; And then sneak into the insulating resin of carbon particle and form to surface applied, this semiconduction continuous slice 13A has for example been applied the non-adhesive linkage of conduct of silicone resin by the inboard in doubling thermal stress absorbed layer 13B constitutes.With the periphery of the semiconduction continuous slice 13A lap wound that constitutes like this, thereby formed semiconduction insulating barrier 13 to main insulating layer 12.
As said insulating resin of sneaking into carbon particle, epoxy resin, mylar, modified polyimide resin etc. are for example arranged.And the base material as carbon particle is adhered to is not limited to polyester non-woven fabric, also can use polyester textile, glass fabric etc., and the resin that becomes the thermal stress absorbed layer 13B of non-adhesive linkage can be a fluorine resin.
Like this, the stator winding that is installed on stator core 78 is received in the vacuum impregnation groove, for example,, insulating resin is impregnated in the gap that each insulating barrier is inside and outside and slot for winding 7G is interior with aqueous insulating resins such as known step vacuum pressed epoxy resin-impregnated.Then, be heating and curing, thereby obtain not producing between stator core 7 and the wire conductor 10 stator 6 in space through making the insulating resin behind the dipping.
As stated, at the varnished insulation resin and make its moment that is heating and curing, stator winding 8 and stator core 7 are by integrated.Then, in reaching the cooling procedure of normal temperature, wire conductor 10, various insulating barrier 11,12,13,15 and stator core 7 are shunk with different coefficient of thermal expansions respectively.But, because because of different coefficient of thermal expansions produces and act on the thermal stress on the thickness of insulating layer direction, absorbed by the non-adhesive linkage of the thermal stress absorbed layer 13B in the semiconduction insulating barrier 13, so, in main insulating layer 12, can not produce and peel off or chap.
On the other hand; Semiconduction insulating barrier 13 is stripped from because of the non-adhesive linkage of thermal stress absorbed layer 13B; But owing to the semiconduction continuous slice 13A lap wound of doubling is electrically connected, therefore, semiconduction insulating barrier 13 can be maintained equipotential across the stripping portion of non-adhesive linkage up and down with it.As a result, even produce stripping portion, corona discharge can not take place in the there yet.And then even produce stripping portion, machinery is also bonding continuously owing to the semiconduction continuous slice 13A lap wound of doubling, and therefore, semiconduction continuous slice 13A can rupture continuously midway.As a result, main insulating layer 12 is adhered to stator core 7 securely, can guarantee the endurance to the electromagnetic force of effect on wire conductor 10.
In addition, when the current potential of the wire conductor 10 of stator winding 8 whole when identical, interlayer insulating film 11 expression wire insulation layers.Below identical.
Then, based on Fig. 4 and Fig. 5, second execution mode of electric rotating machine of the present invention is described.Wherein, because the mark identical with Fig. 1～Fig. 3 represented same component parts, therefore omit detailed description once more.
In this execution mode, and the difference of first execution mode is: semiconduction insulating barrier 13 is between interlayer insulating film 11 and main insulating layer 12, be formed with corona shielding layer 17 and dispose new protection insulating barrier 18 in the periphery of corona shielding layer 17 in the periphery of main insulating layer 12.
Because said semiconduction insulating barrier 13 has adopted formation identical with first execution mode and identical winding method, so detailed.
Said corona shielding layer 17 is through sneaking into carbon particle in the base material of polyester non-woven fabric, and then is mixed with the insulating resin of carbon particle to surface applied, and this base material lap wound is formed.Wherein,, epoxy resin, mylar, modified polyimide resin etc. are arranged, and base material is not limited to polyester non-woven fabric, also can uses polyester textile, glass fabric etc. as insulating resin.
Said protection insulating barrier 18 is formed with semiconduction continuous slice 18A, 18B and as the thermal stress absorbed layer 18C of non-adhesive linkage; Said two semiconduction continuous slice 18A, 18B are for example through sneaking into carbon particle in polyester non-woven fabric; And then sneaked into the insulating resin of carbon particle and form to surface applied, said thermal stress absorbed layer 18C forms through between two semiconduction continuous slice 18A, 18B, for example applying silicone resin.Forming the scope of this thermal stress absorbed layer 18C, is the scope of the both sides except the length direction central part of the slot for winding 7G of stator core 7.
Same with first execution mode, after insulating resin, it is heating and curing the stator winding that constitutes like this 8 and stator core 7 one vacuum impregnations.
Then; In reaching the cooling procedure of normal temperature; Because of the difference of the coefficient of thermal expansion of each parts can produce the thermal stress that acts on the thickness of insulating layer direction; But this thermal stress is absorbed by the non-adhesive linkage of the thermal stress absorbed layer 13B in the semiconduction insulating barrier 13, therefore in main insulating layer 12, can not produce to peel off or chap.
On the other hand, at the length direction central part of slot for winding 7G,, therefore, can prevent the length direction top offset of stator winding 8 at slot for winding 7G because stator core 7, protection insulating barrier 18 and corona shielding layer 17 are bonding securely.And, because the coefficient of thermal expansion that produces in the length direction both sides of slot for winding 7G is poor, can be absorbed by the non-adhesive linkage in the protection insulating barrier 18, instant heating stress absorbing layer 18C, therefore, can not make main insulating layer 12 produce deterioration.
And semiconduction insulating barrier 13 is stripped from because of the non-adhesive linkage of thermal stress absorbed layer 13B, but owing to the semiconduction continuous slice 13A lap wound of doubling is electrically connected, therefore, can it be maintained equipotential up and down across the stripping portion of non-adhesive linkage.As a result, even produce stripping portion, corona discharge can not take place in the there yet.And then; Even the generation stripping portion, mechanical type is bonding owing to the semiconduction continuous slice 13A lap wound of doubling, therefore; Semiconduction continuous slice 13A can rupture continuously midway; Thereby wire conductor 10 is adhered to stator core 7 securely through main insulating layer 12 grades, can guarantee the endurance to the electromagnetic force of effect on wire conductor 10.
Fig. 6 representes the 3rd execution mode of electric rotating machine of the present invention, because the mark identical with Fig. 4 and Fig. 5 represented same component parts, therefore omits detailed description once more.
In this execution mode, be: the thermal stress absorbed layer 13C that has elastomer, for example constitutes in the inboard of the semiconduction continuous slice 13A of doubling by the silicone rubber of having sneaked into carbon particle with the difference of second execution mode.
In this execution mode, also can obtain and the equal effect of above-mentioned each execution mode.
Fig. 7 and Fig. 8 represent the 4th execution mode of electric rotating machine of the present invention, because the mark identical with Fig. 1～Fig. 6 represented same component parts, therefore omit detailed description once more.
In this execution mode, the lengthwise dimension of the slot for winding 7G of stator core 7 is shorter than said execution mode, and the thermal stress that on the length direction of stator winding 8, acts on each insulating barrier is little, thereby is fit to the structure little to the influence of main insulating layer 12.
This stator winding 8 is through forming interlayer insulating film 11 on the wire conductor after the wire rod insulation processing 10; And form semiconduction insulating barrier 13 above that; And then form main insulating layer 12 on it, on form corona shielding layer 17 again, and form protection insulating barrier 15 above that and constitute.Then, same with said each execution mode, stator winding 8 being installed under the state of stator core 7, come the varnished insulation resin through vacuum impregnation, the insulating resin of dipping is heating and curing.
In this execution mode, also can obtain and the equal effect of above-mentioned each execution mode.
Fig. 9 representes the variation of the 4th execution mode, makes semiconduction insulating barrier 13 be double-layer structural, and to make the lap wound direction of semiconduction continuous slice 13A be that rightabout is reeled.
Through such coiling semiconduction continuous slice 13A; The length direction effect of stator winding 8, by the thermal expansion difference of wire conductor 10, each insulating barrier, stator core 7 and the displacement of shrinking the thermal stress absorbed layer 13B of the semiconduction insulating barrier 13 that difference causes can not be partial to folk prescription to, but in the even displacement of length direction both end sides along both sides.
Figure 10 representes the 5th execution mode of electric rotating machine of the present invention, because the mark identical with Fig. 1～Fig. 9 represented same component parts, therefore omits detailed description once more.
In this execution mode; Only the length direction central portion at the slot for winding 7G of stator winding 8 forms semiconduction insulating barrier 13; In the both sides of the length direction except that central portion of slot for winding 7G, form by range upon range of thermal stress absorbed layer 18C for double-deck semiconduction continuous slice 18A, protection insulating barrier 18 that 18B constitutes.
Through adopting above-mentioned formation; Except playing the effect identical,, absorbed by the thermal stress absorbed layer 13B of semiconduction insulating barrier 13 and the thermal stress absorbed layer 18C of protection insulating barrier 18 owing to the thermal stress that produces and act on the thickness of insulating layer direction because of the difference of coefficient of thermal expansion with above-mentioned each execution mode; And; The thermal stress that acts on the length direction of slot for winding 7G is protected the thermal stress absorbed layer 18C of insulating barrier 18 to absorb, and therefore, can not make main insulating layer 12 produce deterioration.
Figure 11 representes the 6th execution mode of electric rotating machine of the present invention, because the mark identical with Fig. 4 and Fig. 5 represented same component parts, therefore omits detailed description once more.
This execution mode improves Fig. 4 and second execution mode shown in Figure 5; In second execution mode; Two semiconduction continuous slice 18A, 18B have been utilized as protection insulating barrier 18; But the protection insulating barrier 19 of this execution mode makes a slice semiconduction continuous slice 19A doubling; Side folder is established thermal stress absorbed layer 19B within it, and prepares two groups of such doubling semiconduction continuous slice 19A, makes the broken line of each semiconduction continuous slice 19A be positioned at the length direction central portion of slot for winding 7G.
Through above-mentioned formation, can obtain and the equal effect of said each execution mode.
Figure 12 representes the 7th execution mode of electric rotating machine of the present invention, because the mark identical with Fig. 4 and Fig. 5 represented same component parts, therefore omits detailed description once more.
